There are many ways to keep track of your work and many notions available for this task but I have found that this way is by far the simplest when crocheting in the round.
Remember the tail? I normally keep a pretty long tail (around 15cm) when I cast on.
1. Just before the first stitch after the first round (set up round), I position the tail to the back of the work (not the side facing you). Crochet as normal.
2. Just before the first stitch of the next round, I flip the tail to front of the work (see the arrow closest to the centre). Continue to crochet as normal
* This is the marker for the beginning of the round *
3. Then continue to work the increase rounds until no more increase is required.
4. At the next round, just before the first stitch, I flip the tail over so it is now on the inside of the work (see the arrow near the edge).
5. Keep crocheting in the round until the next increase or decrease round.
When it is all finished, just snip the tail somewhere near the start of the work (circled in blue above), be careful not to cut the actual project! Reach inside, pull the tail through and just leave it sitting inside. All will be hidden once the body is stuffed!
Hope this makes sense! I am hoping to put more tutorials together in the coming months, might even try recording a short clip...
